Process Steps in Detail
Preheating Zone
In the manufacturing process of transport-type tunnel furnaces, the initial step involves the preheating zone. Here, the raw materials or products are gradually heated to a specific temperature before entering the main heating section. This gradual increase in temperature helps in reducing thermal shock and ensures uniform heating throughout the material.
The processing within the preheating zone sets the foundation for subsequent steps by preparing the material for further treatment. It allows for the removal of any moisture content or volatile substances present in the material, making it more receptive to the following heat treatment processes.
Heating Zone
Within the heating zone of tunnel furnaces, the actual manufacturing process takes place. This section is designed to subject the material to high temperatures required for specific metallurgical transformations or material modifications. The controlled environment in this zone enables precise heat application to achieve desired material properties.
During sensor calibration and inspection routines in the heating zone, operators ensure that the furnace maintains optimal conditions for processing. By monitoring and adjusting parameters such as temperature and atmosphere composition, they guarantee consistent and high-quality results.
Cooling Zone
As the material exits the heating zone, it enters the cooling zone for gradual temperature reduction. The controlled cooling process is crucial in preventing rapid cooling-induced stresses and maintaining material integrity post-processing.
